Ammonium chloride is a salt of

Options

A. weak acid and a weak base
B. weak acid and a strong base
C. strong acid and a strong base
D. strong acid and a weak base

Answer

To determine the origin of ammonium chloride (NH4Cl) as a salt, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of Ammonium Chloride**:
Ammonium chloride is represented by the formula NH4Cl. It consists of two ions: NH4⁺ (ammonium ion) and Cl⁻ (chloride ion).

2. **Understand Salt Formation**:
A salt is formed when an acid reacts with a base. In this case, we need to identify which acid and base produce ammonium chloride.

3. **Identify the Acid**:
The chloride ion (Cl⁻) comes from hydrochloric acid (HCl). When HCl dissociates in water, it donates H⁺ ions, resulting in Cl⁻ ions.

4. **Identify the Base**:
The ammonium ion (NH4⁺) comes from ammonium hydroxide (NH4OH). Ammonium hydroxide is a weak base that partially ionizes in solution to produce NH4⁺ and OH⁻ ions.

5. **Write the Reaction**:
The overall reaction can be represented as:
\[ \text{HCl (aq) + NH4OH (aq) } \rightarrow \text{ NH4Cl (aq) + H2O (l)} \]
Here, HCl is the strong acid, and NH4OH is the weak base.

6. **Conclusion**:
Therefore, ammonium chloride (NH4Cl) is the salt formed from the reaction of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH). Since HCl is a strong acid and NH4OH is a weak base, ammonium chloride is classified as a salt of a strong acid and a weak base.

### Final Answer:
Ammonium chloride is a salt of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH), making it a salt of a strong acid and a weak base.
